Description

[Detailed Description of the Invention] The present invention relates to a joystick mechanism capable of two-dimensionally operating two mutually independent electrical quantities with a single joystick.

In particular, the present invention relates to a device for controlling two mutually independent voltages with a single joystick.

Generally, a mechanism shown in FIG. 1 is known as a mechanism for operating two linear sliding type resistors arranged at right angles to each other.

In the mechanism shown in FIG. 1, there is a sliding lever 2 having an elongated hole 4 in the X-1X direction, which controls a variable resistor 1, and a Y-type slide lever 2, which controls a variable resistor 5 arranged at right angles to the variable resistor 1. −
A sliding lever 6 having a hole 7 long in the 1Y-10 direction is provided.

These sliding levers 6.7 are superimposed on each other at right angles to each other, and one joystick 4, whose base 8 can be rotated in all directions, is inserted into both holes 4 and 7.

When using this structure to control the voltage using a resistor, it is necessary to tilt the joystick 3 in the -Y or +Y direction in order to convert the resistance value of the variable resistor 1.

Figures 2a and 1) are sectional views taken along the line A-A in Figure 1 when viewed from the X direction, in which figure a shows the joystick 3 in the neutral position, and figure b shows the joystick 3 in the Y direction. This shows the case when it is defeated.

As is clear from these diagrams, joystick 3
When in the neutral position, the elongated hole 4 is opened as shown in Figure 2a.
The width Wy is preferably equal to the diameter of the joystick 3.

Further, when the joystick 3 is tilted by an angle φ in the Y direction (the same goes for the Y direction), the width Wy of the elongated hole 4 is required.

Here, T represents the thickness of the sliding lever 2.

That is, WY needs to be larger than D. This means that in an actual device, if the joystick 3 is in a neutral position or has a small inclination, backlash will occur between the joystick 3 and the elongated hole 4 or 7, making the operation unstable.

Therefore, an object of the present invention is to provide a mechanism in which two linear sliding variable resistors arranged at right angles to each other are operated by a single joystick, in which a long hole is inserted through which the sliding lever of each variable resistor and the joystick pass. By rotatably attaching the drive levers arranged at right angles to each other, the new system maintains proper engagement regardless of the joystick inclination angle and can operate the variable resistor without backlash. There is a joystick mechanism to provide.

Hereinafter, the present invention will be described by way of examples with reference to the drawings.

FIG. 3 is an overall explanatory perspective view of the joystick mechanism of the present invention. In this figure, variable resistors 11 and 15 are arranged at right angles to each other, and the two resistors 11 and 15 are arranged at right angles to each other for controlling each of these resistors 11 and 15. There are drive levers 12.16 arranged transversely.

These drive levers 12, 16 are provided with elongated holes 14, 17, respectively.

The joystick 13 is inserted into the elongated hole 14.17 and is positioned at its base 18 so as to be rotatable in all directions.

In the present invention, a sliding lever 19 is installed between the variable resistor 11 and the drive lever 12.

Similarly, a sliding lever 21 is attached between the drive lever 19 and the variable resistor 15.

The drive lever 12 has a cylindrical part 20, which is inserted into the sliding lever 21 so as to be rotatable in the horizontal direction, and its tip is bent, for example, as shown in FIG. It will be done.

Further, the sliding lever 19 is secured by fitting together two plates having semicircular grooves and inserting the cylindrical portion 20 into the grooves.

The drive lever 16 and the sliding lever 21 are also combined in the same manner as described above.

Figures 4a and l) show cross-sections taken along line B-B in Figure 4 when the joystick 13 is in the neutral position and when it is tilted by a certain angle, and Figure a shows the state in which the joystick 13 is in the neutral position. .

At this time, the diameter of the joystick 13 and the drive lever 12
The width WY of the elongated hole 14 is approximately the same as the width WY of the elongated hole 14 .

Figure b shows the state when the joystick 13 is tilted; in this case, the drive lever 12 is tilted in accordance with the tilt of the joystick 13, so the joystick 13 is tilted to fit into the elongated hole 14.

That is, even when the joystick 13 is tilted, D=W.
The state is Y.

This shows that the joystick 13 and the length (L14) are always tightly fitted whether the joystick 13 is in the neutral position or tilted, indicating that no backlash occurs.

The relationship between the joystick 13 and the drive lever 16 disposed perpendicularly to the drive lever 12 is also the same as described above.

Next, another embodiment of the drive lever will be described.

In FIG. 5, a drive lever 32 is shown having an elongated hole 34 into which the joystick 13 is fitted, but in this case the elongated hole 34 has a fork shape such that the end opposite the sliding lever 19 is open.

In addition, a notch 35 is provided at the bottom of the long hole 34 on the sliding lever 19 side.
is formed.

This type of drive lever 32 can be elastically opened and closed because the elongated hole 34 has a notch 35.

Therefore, when the joystick 13 is held in the elongated hole 34, a gap can be completely eliminated and the joystick 13 can be held perfectly tightly.

That is, when controlling the variable resistor 11 by tilting the joystick and moving the sliding lever 19, it is possible to completely eliminate backlash.
